STANDARD Chemistry Ionisation Potential MCQ Question
Which of the following relation is correct with respect to first (I) and second (II) ionisation potentials of sodium and magnesium
Iₘg = Iₙₐ
Iₙₐ = Iₘg
Iₘg > Iₙₐ
Iₙₐ > Iₘg
Correct Answer
Detailed Explanation
The first ionisation potential of sodium is less than that of magnesium, but the second ionisation potential of sodium is greater due to the removal of an electron from a stable noble gas configuration.
